Overview of Coupling Types: Functions, Advantages, and Limitations

The role of the coupling is used to connect different institutions in the main shaft and the slave shaft, so that two different institutions can jointly rotate and transfer torque, part of the coupling and change, vibration damping and improve the dynamic performance of the role of the shaft system.

Coupling has two parts, divided into the active shaft and the slave shaft connection, general power machine, most of the coupling with the help of the working machine connected to the mechanical products, shaft transmission China, the most commonly used connecting parts.

Commonly used couplings are diaphragm couplings, tooth couplings, plum blossom couplings, slider couplings, drum tooth couplings, universal couplings, flexible couplings, serpentine spring couplings and so on.

The advantages of diaphragm coupling are high precision transmission, good compensation, high torque transmission, zero clearance transmission, easy maintenance. Disadvantages of limited adaptability to the environment, overload capacity is relatively weak, high cost.

The advantages of the tooth coupling for the transmission of torque, good compensation, high transmission efficiency, reliable, relatively simple maintenance. Disadvantages of the installation of high precision requirements, the need for good lubrication and sealing, high processing costs, the weight of the product is large.

The advantages of plum blossom coupling for the compensation ability, better elasticity, simple and compact structure, wide range of transmission torque. Disadvantages of the elastic element is easy to damage, more sensitive to the temperature, the transmission precision is limited.

The advantages of the slider coupling for the compensation of displacement ability, simple and compact structure, transmitting torque, buffer vibration absorption is good, relatively low cost. Disadvantages are not suitable for high-speed transmission, serious wear and tear of the slider, transmission efficiency is low, the installation of high precision requiremen
